Cellulose nanocrystal-assisted microphase separation for constructing multi-scale electrospun membrane toward W/O emulsion separation.

Efficient separation of water-in-oil (W/O) emulsions is essential for wastewater treatment, yet conventional electrospun membranes often suffer from poor mechanical properties, large inter-fiber pores and structural instability. Here, we propose a coaxial electrospinning strategy that combines a PVDF/CNC core with a PDMS shell to construct a hierarchical superhydrophobic membrane. The incorporation of CNC induces nonsolvent-driven microphase separation during electrospinning, generating spindle- and nanosphere-like surface structures while reinforcing the fibrous network.

Wooden ionogel with simultaneous sorption-desorption functionality enabling 24-hour continuous atmospheric water production.

Sorption-based atmospheric water harvesting (SAWH) offers a promising solution to address freshwater scarcity. Although many solid sorbents exhibit high water uptake capacities, their ability to achieve continuous, all-day water production still depends on complex system configurations. Here, a 24-h SAWH system is presented, enabled by wood-based ionogel (WIG) with simultaneous sorption-desorption functionality.

Unlabelled: Root-knot nematodes (RKNs) are notoriously challenging to control because of their broad host spectrum and swift proliferation. Consequently, there is an urgent need to develop safe and effective nematicides. Microorganisms and their metabolites have the potential to control RKNs safely and effectively.

Combined Effect of Resting Time and NaHCO on Solubility and Gel Properties of Low-Salt Chicken Myofibrillar Protein.

To investigate the interaction effects of resting times (0, 6, and 12 h) and NaHCO concentrations (0, 2, 4, and 6 g/kg) on chicken myofibrillar protein (CMP), this study analyzed the changes in solubility, active sulfhydryl groups, rheological behavior, fluorescence, and gel properties of CMP solutions (60 mg/mL). The results indicated that pH significantly increased with higher NaHCO concentrations and longer resting times. Consequently, solubility, active sulfhydryl groups, apparent viscosity, shear stress, G' value at 80 °C, hardness, springiness, and cohesiveness all significantly increased, while particle size, turbidity, and whiteness significantly decreased.

Hybrid Nanofiber-Based Atmospheric Water Harvesters: Sunlight-Driven Operation in Low-Humidity and Low-Illumination Environments.

Aerogels incorporating hygroscopic salts have been widely explored for atmospheric water harvesting (AWH). However, the scalability of these sorbents remains limited due to their reliance on energy-intensive and time-consuming drying methods such as lyophilization or supercritical drying. Here, we present a simple and scalable approach to drying hydrogels with desirable AWH properties using a freezing process followed by solvent exchange and thawing at room temperature.

Y-Doped HfO Ferroelectric Memristor for Information Processing and Neuromorphic Computing.

Memristors have garnered significant attention due to their potential for multilevel storage and synaptic learning capabilities. However, the variability in forming and breaking conductive pathways in conventional memristors restricts their application in simulating neural synapses. The resistive switching in ferroelectric memristors is driven by stable ferroelectric switching, effectively avoiding the issues.

Engineering transverse cell deformation of bamboo by controlling localized moisture content.

Bamboo's native structure, defined by the vertical growth pattern of its vascular bundles and parenchyma cell tissue, limits its application in advanced engineering materials. Here we show an innovative method that controls localized moisture content to shape natural bamboo into a versatile three-dimensional (3D) structural product. Different temperatures along the transverse direction of bamboo were used to induce directional water transport within the bamboo, so that the distribution of internal stress was shifted from the bamboo surface to the inner layers.

However, research on the dual-function mechanism of 2-undecanone remains relatively limited.

Peptide-Modified Lipid Nanoparticles Boost the Antitumor Efficacy of RNA Therapeutics.

RNA therapeutics offer a promising approach to cancer treatment by precisely regulating cancer-related genes. While lipid nanoparticles (LNPs) are currently the most advanced nonviral clinically approved vectors for RNA therapeutics, their antitumor efficacy is limited by their unspecific hepatic accumulation after systemic administration. Thus, there is an urgent need to enhance the delivery efficiency of LNPs to target tumor-residing tissues.

Selective Emission Fabric for Indoor and Outdoor Passive Radiative Cooling in Personal Thermal Management.

Radiative cooling fabric creates a thermally comfortable environment without energy input, providing a sustainable approach to personal thermal management. However, most currently reported fabrics mainly focus on outdoor cooling, ignoring to achieve simultaneous cooling both indoors and outdoors, thereby weakening the overall cooling performance. Herein, a full-scale structure fabric with selective emission properties is constructed for simultaneous indoor and outdoor cooling.

[Directed evolution improves the catalytic activity of laccase in papermaking].

As a biocatalyst, laccase has been widely studied and applied in the papermaking industry. However, the low catalytic efficiency and poor stability of natural laccase limit its application in the pulping process. To develop the laccase with high activity and strong tolerance, we carried out directed evolution for modification of the laccase derived from and screened out the mutants F282L/F306L and Q275P from the random mutant library by high-throughput screening.

Biobleaching is an eco-friendly strategy that can reduce costs and pollution in the pulp and paper industry. Herein, an effective biobleaching approach was proposed using a novel multi-enzyme complex. The multi-enzyme complex was constructed based on mini-cellulosome scaffolding protein integrated with laccase (BpLac) and xylanase (BpXyn) from Bacillus pumilus.

Nematodes exposed to furfural acetone exhibit a species-specific vacuolar H-ATPase response.

Furfural acetone (FAc) is widely used as an additive by the food industry, as well as an intermediate in several fine chemical industries. Its nematicidal activity against the free-living model organism Caenorhabditis elegans and the parasitic nematode Meloidogyne incognita are well known, but its molecular mechanism of action remains unclear. To deep this subject, we performed 48-h lethal tests on eight nematode species, encompassing free-living, plant-parasitic, and animal-parasitic nematodes.

In this study, the effects of pyridine and quinoline degradation on NH-N removal under phenol stress were evaluated using three lab-scale sequencing batch reactors.

Engineering Glucosamine-6-Phosphate Synthase to Achieve Efficient One-Step Biosynthesis of Glucosamine.

As an important functional monosaccharide, glucosamine (GlcN) is widely used in fields such as medicine, food nutrition, and health care. Here, we report a distinct GlcN biosynthesis method that utilizes engineered glucosamine-6-phosphate synthase (GlmS) to convert D-fructose to directly generate GlcN. The best variant obtained by using a combinatorial active-site saturation test/iterative saturation mutagenesis (CAST/ISM) strategy was a quadruple mutant S596D/V597G/S347H/G299Q (GlmS-BK19), which has a catalytic activity 1736-fold that of the wild type toward D-fructose.

Composites based on electrospun fibers modified with cellulose nanocrystals and SiO for selective oil/water separation.

Membranes for water remediation require structural stability, efficient operation, and durability. In this work, we used cellulose nanocrystals (CNC) to reinforce hierarchical nanofibrous membranes based on polyacrylonitrile (PAN). Hydrolysis of the electrospun nanofibers (H-PAN) enabled hydrogen bonding with CNC and provided reactive sites for grafting cationic polyethyleneimine (PEI).

Multiple Receptors Contribute to the Attractive Response of Caenorhabditis elegans to Pathogenic Bacteria.

Nematodes feed mainly on bacteria and sense volatile signals through their chemosensory system to distinguish food from pathogens. Although nematodes recognizing bacteria by volatile metabolites are ubiquitous, little is known of the associated molecular mechanism. Here, we show that the antinematode bacterium Paenibacillus polymyxa KM2501-1 exhibits an attractive effect on Caenorhabditis elegans via volatile metabolites, of which furfural acetone (FAc) acts as a broad-spectrum nematode attractant.

The cellulose was valorized by forming cellulose nanocrystals (CNCs) through simple bleaching and ultrasonication processes.
